As a patrol and escort ship, Brooks operated between California, Washington, and Alaska during the first year of World War II.

On 1 December 1942 her classification was changed to APD 10 and she was assigned to the South Pacific.
She served as a transport and minesweeper during the Lae, New Guinea, landings (4–14 September 1943); Finschhafen, New Guinea, landings (22 and 29–30 September); Cape Gloucester, New Britain, assault (26 and 28–29 December); Saidor, New Guinea, landings (2 January–17 February 1944); Admiralty Islands landings (29 February–5 March and 19 March); Hollandia, New Guinea, assault (22–28 April); capture of Saipan (14–22 June); Leyte occupation (18 November–4 December); Mindoro invasion (12–18 December); and the Lingayen Gulf, Luzon, landings (3–6 January 1945).
On 6 January 1945 a Japanese suicide plane crashed into Brooks’ port side starting a fire amidships. The main and auxiliary steam lines were severed; the fire main broken; and the sea valve to the condenser was pierced, causing the forward engine room to flood. Three of Brooks’ crew were killed and 11 wounded. She was towed to San Pedro, Calif., by SS Watch Hill and decommissioned there 2 August 1945. Brooks was sold 30 January 1946.
